i found this from peter's old message:
_*4) Broken in-dialog routing when using outbound
*_*Detail:* In-dialog requests (including ACK and BYE) are incorrectly
routed when outbound is used (issued identified by Olle during SIPit)
*Status:* The bug is in the loose routing code in the rr module. I now
have a test system for this here and will work on this issue once issues
1 and 2 are finished.
perhaps the issue that i noticed with loose_route() on in-dialog request
has something to do with the above.
